@nick.lloyd Thankyou...i'll try the last version, reading forums people says HP was problematic, thats why i was asking for help.

Hi,
I´ve and old HP ProLiant DL160 G6 server, my intention is use it for homelab, its possible to install XCP-ng hypervisor? any suggested version? It has ESXi 5.1 installed, with some VMs of the old company...but i cant access using vSphere Client o connect using VMware Workstation, an error jumps! So I find this hypervisor, but im a noob. Thankyou!!
